Abstract: 1,144,932. Hulling and cleaning seeds. NATIONAL RESEARCH DEVELOPMENT CORP. 13 June, 1967 [19 April, 1966], No. 17192/66. Heading A2Q. Apparatus, Figs. 1 and 2, for hulling seeds, particularly small, light seeds such as seeds of timothy grass and clover, comprises a vortex chamber 1, into which a current of gas, e.g. -air, at 2/3 p.s.i. above atmospheric pressure and flowing at a speed between 10,000 and 18,000 feet per minute, is fed tangentially through an inlet port 11 connected by a conduit 9 to a fan or fans (not shown). The vortex chamber 1 may be cylindrical, as shown. The seeds to be hulled are fed into the whirling gas in the vortex chamber through an opening 3 in an end-wall 2. The seeds may be conveyed to the opening 3 by a travelling conveyer 7 and shoot 5, as shown, or by a rotating auger (47) Figs. 3, 4 and 5 (not shown). At least part of the inner surface of the vortex chamber has abrasive properties. For example, the inner, peripheral surface of the vortex chamber 1 may be lined with a replaceable strip of paper 13 faced with abrasive garnet chips. At the other end of the vortex chamber is located an annular baffle 15, which defines an axial discharge opening for the current of gas, which opening is smaller in diameter than that part of the vortex chamber having the abrasive surface. The discharged gas and entrained, treated seed material, namely hulled seeds, detached hulls and recalcitrant seeds having hulls still attached, pass into a setling chamber 17 having an arcuate, perforated upper periphery 17C, through which gas is discharged, and an open bottom leading to a shoot 17B, through which the seed material passes to cleaning and separating devices, where hulled seeds, hulls and unhulled recalcitrant seeds are separated. The latter may be returned to the vortex chamber. Alternatively, the treated seed material may pass from the chamber 17 through outlets (33) and (35), Fig. 4 (not shown) into bags.

Title: Diffusion apparatus for separating gases
IPC: B01D53/22
Filed: 1949-06-29
Abstract: In a diffusion unit for separating gases wherein the feed gas and a sweep gas, e.g. steam, are passed respectively through the alternate spaces between a plurality of porous rectangular diaphragms spaced apart by detachable frames, the unit is so designed that the feed and sweep gases passing through adjacent spaces flow at right angles to one another.  As shown, square frames 25 (Figs. 1 and 5) separating the diaphragms 35 have two <PICT:0658316/III/1> <PICT:0658316/III/2> <PICT:0658316/III/3> <PICT:0658316/III/4> closed or solid opposite side members 26 and two open opposite side members 27 and the assembly of frames is so arranged that a closed side member alternates with an open side member.  The frame and diaphragm assembly, held in position by tie bolts 31 and by inter-engaging pins 28 and holes 29, is supported on brackets 16 (Fig. 2) in a cylindrical shell 10, the interior of which is divided into four compartments by radially extending partitions 15.  Each compartment is provided with a gas inlet or outlet 61-64 and to maintain uniform pressure conditions perforated gas distributing members 66 are also provided.  Feed gas enters, for example, the upper compartment at 61, passes through alternate spaces between the diaphragms 35 and leaves the bottom compartment at 63, in which case sweep gas enters a side compartment at 62 and leaves the opposite compartment at 64.  Either gas may flow upwardly, downwardly or across the unit.  The frames are divided into two assemblies closed by end plates 34, the inner end of each bearing upon the plate 20 and the outer end upon the discs 50. Each frame has a centrally disposed brace 36 (Fig. 3), which serves to prevent vibration of the diaphragm.  Sealing means 43-45 (Fig. 3), adjacent supports 16 are provided to prevent leakage of gas between the various compartments.  In a modification, the frames and diaphragms are oblong instead of square so as to vary the length of the path of travel of the feed gas with respect to the sweep gas.
